This invention relates to a metal side door for railroad cars, andconcerns itself primarily with means `for supporting the door.

It is well lmown that railroad cars Ain transit are subjected to severestrains and the doors are subjected to severe usage.- Itfrequentlyhappens that great diiculty is encountered in opening andclosing the doors on account of the deformation ue to tor- .sionalstrain or the like, which is imparted to lustrate a preferredembodimentof this invention and in which similar reference numeralsrefer to similar parts in the different views:

As shown on the drawings:

In order to explain and illustrate the application of this inventionthere is shown a portion of a railway car 1 having a doorway 2. Attachedto the car adjacent the upper l edge 0f the doorway there is a guide 3adapted for receiving a. guideway 4 upon a sliding door 5 which isadapted for closing the doorway. The guide 3 and guidewa 4 are s0constructed as to provide both siding and vertical movement. for 'thedoor and for movl'Ils ing the door inwardly at closing position. In

the present instance the guide 3 is shown .as l

comprising an an ular member having one flange 3a attache to the car, aweb 3b at right angles to the car, and a depending guide flange 3c,which cooperates with the guideways 4 on the door. This de nding liange3c is provided with a pair o indentures 3d which cooperate with theguideways 4 which are shown as comprising a pair of U-shaped clips.

Adjacent the lower end of the doorway there is a horizontal track 6which is shown as consisting of an angle bar having one flange attachedto suitable'brackets 7 extending from the stringers 8 and a horizontaliiange which forms a track.

Adjacent the lower end of the `door 5\are a pair of roller frames 9which are pivoted to the door at their remote ends as indicated at 10.Each roller frame supports a roller 11 intermediate its ends. The inneror adjacent ends of the roller frame 9 are pivoted to a link 12,- whichin turn is pivoted at its upper end to a lever 13 which is pivoted atits lower end 14 to the door. With reference to Figure 3 it will beno'ted that the lever 13 is rigid with its pivot 14 which extendsthrough a suitable casin 5a attached to the door, the inner end of thepivot being provided with an arm 14a to which the link 12 is pivoted.`It will be noted that the connection of the link 12 with the arm 14a islocated above the pivot point 14 of the lever. When this lever is movedinto horizontal position as shown in Figure 7, the door will be elevated`and will be supported by the rollers on the track. However, when thelever 13 is moved into vertical position as shown in Figure 8 the rollerframes will be elevated or swung upwardly, disen aging the rollers fromt e track 6 where y the door will be supported by its base angle 16resting upon the track.

It should be noted that the lever 13 is upon dead center when therollers' are elevated above the lower ed of the door.

When the door is operated, itis desirable to kee the same from scrapingagainst'the side o the car and for this purpose there is rovided aswitching member 17 shown in igures 4, 5 and 11. It will be noted thatthis switching member has an outwardly curved surface 18 which isadapted to be endoor when it is moved a short v ance beyond its closedposition as shown in Figure 5 for laterally moving the door outwardlyfrom the side ofthe car.

At the front end of the door opening there is provided a weather strip19 having an outwardly sloping iange beneath which the front edge of thedoor 1s adapted to engage when the door is in closed position, and uponthe rear end of the door there is a deformed angular member 20 which isadapted to engage an angle member 21 secured to the rear ofthe car, thedoor and car being provided with cooperating means 22 and Y23 as shownin Figure 4, for drawing the door inwardly against the side of the carwhen the same is in closed position. The featuresset forth 'in thisparagraph are alreadywell known, and require no further description.

Upon the bottom of casting 24 which is adapted to be engaged by theportion of the door which depends below the track when the door is movedto closed position for cooperating);l with such door for guiding thesame into its closed position.

In oi'der to close the door tightly, closing mechanism has been shown inFigure 1, which consists of a lever 25 pivoted intermediate its ends tothe door and provided 13 is swung into horizontal position as shown inFigure 7, for moving the rollers into contact with the track andelevating the door above said rollers. It will then be possible to movethe door to and fro. When the door is opened, the guideway clips 4 willride out of their indentures 3d and thus move the upper part of the doorout of contact with the side of the car. At about the same time the doorwill engage the switching member 17 whereby the lower portion of thedoor will be moved outwardly and free of the side of the car. When thedoor is closed the indentures 3d and the parts 22, 23 and 24 will causethe door to move inwardly. Consequently there are upper and lower `meansfor moving the door outwardly and upper and lower means or indenturesfor moving the door inwardly. If at any time it is desirable to supportthe door directly on the tracks' as for example when it is in closedposition the lever 13 may be swung into vertical position as shown inFigure 8 for elevating the rollers above the lower ed e of the doorwhereby the lower edge of te door may rest directly upon the track.

We are aware that man changes may be made and numerous detai s ofconstruction may be varied through a wide range without departing fromthe principles of this invention and we, therefore, do not purposelimiting the patent granted hereon, otherwise than necessitated by theprior art.

We claim 'as our invention:
